In English:
Not trying to offend you but building a speed controler for a heavyweight is very difficult unless you just want on and off control.

Unless you are an electronic engineer I would not try to build a proportional speed controler.

Here is an on off reverse speed controler diagram by bugs:

Ed in italiano
Sta provando ad offenderlo ma sviluppando un controler di velocit per un heavyweight molto difficile a meno che desideriate appena il controllo avanti/stop.

A meno che siate un assistente tecnico elettronico non proverei a costruire un proporzionale accelero il controler.

Qui ¨ sopra fuori dello schema dinversione del controler di velocit dagli Bugs: http://www.bugs.nl/media/source/projects/speedo/relay-layout.jpghttp://www.bugs.nl/media/source/proj...lay-layout.jpg
